10 tips for radiant skin thanks to innovative actives

• Always apply polyglutamic acid to clean, slightly damp skin

This allows the ingredient to trap moisture immediately and prepare the skin optimally. On damp skin, polyglutamic acid forms an invisible protective film that reduces water loss and makes the skin appear plumper. This step is crucial if you want to achieve maximum hydration.

• Use polyglutamic acid morning and evening

The ingredient is not light-sensitive and is therefore suitable for daily use at any time of day. Be sure to pair it with a broad-spectrum sunscreen in the morning to further strengthen the skin barrier and protect against environmental damage.

• Use the right amount of product for optimal results

For a serum, three to seven drops are enough, gently distributed over the face and neck. For a cream, a pea-sized amount is sufficient. Less is more: a thin layer works more effectively and prevents over-conditioning or shine.

• Combine polyglutamic acid with hyaluronic acid for a maximum hydration boost

These two ingredients are a true power duo. Hyaluronic acid pulls water into the skin while polyglutamic acid binds it at the surface like a protective net. This synergy delivers long-lasting hydrated, smooth and plump skin – ideal for any skincare routine.

• Support dry or sensitive areas with targeted local application

Polyglutamic acid is excellent for areas prone to pronounced dryness, such as the cheeks, forehead or around the nose. A spot application helps relieve tightness more quickly and stabilise the skin barrier.

• Use polyglutamic acid as a complementary moisture shield with retinol, AHA and BHA

If your routine includes potent active ingredients, polyglutamic acid protects the skin from additional drying. It envelops the skin in a gentle, non-sticky film and prevents irritation – especially valuable for sensitive or mature skin.

• Choose the formulation that suits your needs

Serums are more concentrated and suited to dehydrated skin, while creams are ideal if you prefer a richer layer. For hands, feet or lower legs, choose a body cream with polyglutamic acid to target dry or irritated areas specifically.

• Pay attention to effective concentrations – at least 0.3 %, maximum 3 %

Too low concentrations show little effect, too high can weaken the skin barrier. High-quality pharmacy products usually offer a well-balanced formulation that combines safety and efficacy.

• Patch-test new products first to check tolerability

A short patch test on the inner arm helps rule out potential irritation early. This step is especially important for sensitive skin to expand your routine safely and in a controlled way.

• Never use polyglutamic acid pure; always use it in tested formulations

Undiluted acids can irritate the skin. Therefore, choose professionally made serums or creams that provide the correct concentration and stable formulations. In pharmacies and drugstores you will find high-quality products specifically designed for this purpose.
